Delapan-Delapan is optimal, (2) Whether the method of EOQ (Economic Order Quantity) minimize s the production cost in CV. Delapan-Delapan, (3) how many optimal order of raw material at CV. Delapan-Delapan, (4) the amount of safety stock at CV. Delapan-Delapan, and (5) The time the CV. Delapan-Delapan do the Re Order Point if the company applies EOQ policy.
